(7) Set an engine tachometer.
NOTE:
l For engine tachometer setting procedure, refer to
GROUP 9
-
Service Adjustment Procedures.
(8) Connect the negative cable of the battery.
(9) Place the ignition switch at “ON” and check that the
voltmeter reading is equal to the battery voltage.
NOTE:
When the voltmeter reading is OV, an open-circuited wiring
or fusible link between terminal S of the generator and the
positive terminal of the battery is suspected.
(10)Check to ensure that all of the lamps and accessories are
“OFF”.
(1 l)Start the engine.
(12)lncrease the engine speed to 2,500 rpm.
(13)When the output current of the generator has decreased to
less than
IOA,
read the value indicated by the voltmeter.
(14)lf the reading is equal to a value in the regulator voltage
table, it follows that the voltage regulator is performing
well. If the reading is out of the standard limits, the voltage
regulator or generator is out of order.

(15)After the test has been completed, let the engine run at
idle.
(16)Place
the ignition switch at “OFF”.
(17)Disconnect the negative cable of the battery.

the test ammeter, voltmeter and engine tacho-
meter.
